You have certain long-term financial goals in mind and you also have a certain tolerance for risk when it comes to investing your money. Consider using the following investment strategies and products along with the guidance of your investment professional to help you find your balancing points.

Allocate your assets across the major asset classes stocks, bonds, and cash to help pursue the optimal returns for the risk level you’re willing to undertake. Diversify within each asset class to take advantage of different investment styles such as growth and value stocks and market sectors such as both government and corporate bonds. Rebalance regularly. Market activity can shift your portfolio allocations. Rebalancing helps you maintain your desired allocation.

Target date strategies

Nine of the MFS Lifetime Funds have target maturity dates 2055, 2050, 2045, 2040, 2035, 2030, 2025, 2020, and 2015 allowing you to choose the time horizon that works best for your specific financial goals consistent with the approximate retirement year in the funds name. These funds automatically rebalance their holdings over time, shifting from more aggressive investments early to more conservative investments as the target date nears. The MFS Lifetime Income Fund is geared toward investors who have already reached their target dates. The principal value of the fund options are not guaranteed at any time; the funds’ objectives and investment strategies change from one target date to another.

Important risk considerations for MFS Conservative, Moderate, Growth, and Aggressive Growth Allocation Funds. The fund may not achieve its objective and/or you could lose money on your investment in the fund. Stock markets and investments in individual stocks are volatile and can decline significantly in response to issuer, market, economic, industry, political, regulatory, geopolitical, and other conditions. Investments in debt instruments may decline in value as the result of declines in the credit quality of the issuer, borrower, counterparty, or other entity responsible for payment, underlying collateral, or changes in economic, industry, political, issuer-specific, or other conditions. Certain types of debt instruments can be more sensitive to these factors and therefore more volatile. In addition, debt instruments entail interest rate risk (as interest rates rise, prices usually fall), therefore the Fund’s share price may decline during rising rate environments as the underlying debt instruments in the portfolio adjust to the rise in rates. Funds that consist of debt instruments with longer durations are generally more sensitive to a rise in interest rates than those with shorter durations. At times, and particularly during periods of market turmoil, all or a large portion of segments of the market may not have an active trading market. As a result, it may be difficult to value these investments and it may not be possible to sell a particular investment or type of investment at any particular time or at an acceptable price. 1 Investments in foreign markets can involve greater risk and volatility than U.S. investments because of adverse market, economic, industry, political, regulatory, geopolitical, or other conditions. Investments in small-cap companies can be more volatile than investments in larger companies. MFS strategy of investing in underlying funds exposes the fund to the risks of the underlying funds.
